Specification of Letters Patent.

Patented June 28, 1921.

Qriginal application filed July 18, 1919, Serial No. 311,82. Divided and this application filed May 17, 1920. Serial No. 382,112.

To all 00/) cm it may concern:

Be it known that we, Ennnsr Jonnson, residing at Gary, in the county of Lake and rfltate o'l lndiana, and ARTHUR Nonnonisr, rsiding at Gary, in the county of Lake and to of lniiliana, both citizens of the United totes ot' America, have invented a certain low and useful Improvement in Cokevons, oi? which the following is a specification.

This invention relates to coke ovens. The object of the invention is to provide a coke even so constructed. that the material delirered into the oven is much more evenly distributed in the oven than has heretofore been possible, thus doing away with the large amount of labor heretofore required in spreading the material after it has been delivered into the oven, and in cleaning up the coal on top of the oven after the charging operation. ll. further object is to so construct the device that a much larger volume oi. material. may be charged at one time, thus greatly saving the time the oven is out oi commission, and therefore increasii efficiency. It further object of the invention is to entirely do away witl the lending machine which in prior constructions have had to work through openings in the end ot' the oven to level off the material delivered into it.

The inventi n consists in mechanism tor mirrying or the foregoing objects which can and comparatively cheaply be. c: mule, which is very e'iiicient and satisi acy in operation, and is not liable to get out 1): ru er. More particularly the invention consists in many features and; details of construction hereafter more fully set forth in the spocificz'ation and claims.

Referring to the drawings, in which similar numerals represent the same parts throughout the several views,

nigure. 1 is a side elevation partially insei'wtion o'l the improved coke oven of this invention showing the rails on which the charging mechanism therefor travels over the oven as more fully described and claimed in our original. application, Serial Number 311,824, filed July 18, 1919, of which this application is a division. In this view the oven doors are removed.

2 is an end view of the oven showing the manner in which a plurality of chambers such as appear in section in Fig. 1 are arranged.

big. 3 is an enlarged detail taken at the upper central portion of Fig. 1.

Fig. 1 is a sectional side view similar to Fig. 3 showing the oven door in closed position.

big. 5 is a sectional end view on the irregular line of Fig. 4.

As is well understood in the art, a coke oven battery as a whole consists of a plurality 01' coal chambers made relatively thin in one direction, say 16 inches, and long in the other, say 30 or 40 feet, in which coal is placed and heated by mechanism placed between said chambers forming no part of this invention. In prior constructions it has been customary to root each of these compart-, ments with solid briclr perforated at intervals, with holes through which coal is delivered, said coal falling in conical piles at intervals along the coal chambers from which condition it had to be leveled off by mechanism ordinarily operating through the end 01 the coal chamber at considerable trouble and expense. Furthermore, an op era-tor had to walk along the top of each coal chamber, and sweep the surplus material left on the top in the process of delivering coal, into it, and then put in by hand circular covers to close the coal chamber preparatory to the operation of coke making. in the construction shown in this application, the upper or root section of the coal chamber is replaced by a compartment having at its extreme ends a diagrammatically indicated wall 1 1, Fig. 1, connected by long parallel side walls 16 rising from the top portion 18 of the coal chamber proper and open continuously into such coal chamber. This top or supplemental roof passage is of approximately the dimensions of the coal chamber to be filled and as the lengths of the side walls 16 are therefore substantial it is necessary to tie them together. This is done by two classes of intermediate walls; 20, having through them gas passages 22 and carrying at their tops track rails 24 over which the charging machine passes; and 26 preferably sharpened at their tops in points 28 to assist in tying and bracing the walls of the coal chamber and in breaking up and V distributing the mass of powdered coal passing down through the roof box 14-16 into.

the coal chamber proper.

It will, of course, be understood that the coke oven battery proper consists of a multiplicity of such coal chambers placed side by side and consequently there are a plurality of these roof passages, one for each coal chamber, placed side by side as clearly appears in Fig. 2. Adjacent chamber walls are tied together by metallic tie rods 82 which, in the case of the walls carrying the rails 24, lie immediately below the rails, as shown in Figs. 1 and 3. In Fig. 2, the numeral 3% indicates conventionally and not necessarily accurately the flue from the heating chambers (not shown) which are in. the complete furnace or oven forming no part of this invention, placed between the adjacent coal chambers.

The rectangular top openings left between the walls 16 and the walls 20 are selectively closable by rectangular doors or covers 36 which are in the construction heretofore used about 9 inches wide and 8 feet long, and are equipped with downwardly beveled edges 38 to insure a tight fit when lowered to place as shown in Figs. 4- and 5.

Considering the oven construction thus far described, it will be seen that by pass.

ing a proper machine such as is shown in the drawings-of said original application over the oven top and dumping coal uniformly along the rectangular openings closed by these covers 36, a stream of coal substantially the length of the coal chamber can be delivered into it and that said coal in passing downward through said openings to and through the passages will engage the points 28 of the walls 26 and be broken up andthus fall in as near'as possible an even shower into the coal pit below, with the result that the resulting pile in the coal chamber will be nearly, if not quite evenly distributed and require practically no leveling. Even if some manual leveling be required, the openings closed by the covers 36 are so much larger than the circular holes heretofore provided that such inanualleveling is greatly facilitated with consequent saving of time and energy.

In order to obtain the advantages of the oven roof construction just described, a charging mechanism isprovided carried by a car traveling along the rails 24:, heretofore referred to, said car being of such dimensions that all of the charging openings of a single coal chamber may be simultaneously charged with coal. 7

The coke oven of this invention is especially advantageous when equipped and used with the coal carrying and charging car shown, described and claimed in the original application of which this application is a division.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is 1. In combination with the body of a coal receptacle of a coke oven battery, a passage leading to the receptacle at the top thereof of substantially the dimensions of the body of the receptacle, transverse members across said opening adapted to tie and brace the walls of the coal receptacle and a cover insertible in and removable from said passage.

2. In mechanism of the class described, an entrance passage for the top of a coal chamber of substantially the same effective size as the horizontal section of the chamber bounded by box shaped retaining walls affording a relatively narrow and very long passage, intervening tie walls between the longer walls, doors closing the entrance passages formed between the regular longer walls and said intervening tie walls, and a plurality of alined covers, one for each of said so formed openings.
